Dr. Gemma Walton has been researching the area of gut microbiology for 13 years, starting with a PhD investigating bowel cancer and the microbiota. Since this Gemma has been fascinated by the role played by microbes in health and disease of humans and this has shaped her research career. Gemma has conducted different human studies looking at the ageing gut microbiota, the impact of prebiotics on those with metabolic syndrome and how different food products may act as potential prebiotics. Gemma is also adept in using in vitro models, which are great tools for learning more about mixed microbial communities. The potential for the gut bacteria to shape our lives is huge – we are only beginning to understand this potential.
